Andreas Cadhalpun	ef7fe9851e	aacps: avoid division by zero in stereo_processing This fixes a SIGFPE crash in the aac_fixed decoder. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>	9 years ago
James Almer	9dcaae70f2	x86/aacpsdsp: add SSE and SSE3 optimized functions Between 1.5 and 2.5 times faster Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: James Almer <jamrial@gmail.com>	10 years ago

Djordje Pesut	5fd81cf6f0	avcodec: Implementation of AAC_fixed_decoder (PS-module) Add fixed point implementation. Signed-off-by: Nedeljko Babic <nedeljko.babic@imgtec.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Reimar Döffinger	de6d44829c	aacps.c: Move large arrays to context to reduce stack usage. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Vittorio Giovara	16c7a8a142	aacps: invert the order of parameters of ipdopd_reset() This is the order that the caller uses in the rest of the file. The same operation is applied to both parameters, so this change is only done for consistency, it doesn't change the actual behaviour. Bug-Id: CID 732285 / CID 732286	10 years ago
Michael Niedermayer	6433b393ba	avcodec/aacps: fix number of bands used with ipd/opd Fixes use of uninitialized memory Fixes: msan_uninit-mem_7f861d16355f_1664_File1_fixed.aac Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Michael Niedermayer	9f36ec6aa9	aacps: fix order of operands of ipdopd_reset(). With the current implementation this is purely cosmetic Fixes CID732285 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Alex Converse	a237b38021	aac: Reset PS parameters on header decode failure. If the next header frame codes zero envelopes the previous frame's values will be used. Consequently the invalid values must be cleared. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Diego Biurrun	d0fcf39f0c	doxygen: Move function documentation into the macro generating the function. This fixes a bunch of related warnings where Doxygen assumed that the documentation belonged to the macro and not the function.	14 years ago

Alex Converse	d23077af56	Allow PS envelope fixup when ps->num_env_old <= 1. It is already rejected by the "source >= 0 && source != ps->num_env" 0 envelope case and is perfectly legally for the suppressed final envelope case.
